Instead of going to the AG, I would recommend contacting the FCC. This prompts quick action and even just telling a Comcast rep that you're going to contact the FCC can be helpful.
Comcast makes it very difficult to get support if you don't lease one of their modems. Literally every time I call they insist that the problem is my modem, and of course it never is. All of my issues have been either outages or congestion-related, but Comcast reps can't fix the former and will never admit to the latter. So instead they blame your modem and ask for 10 bucks a month to lease a modem from them.
